But look at some of these old "For Sale" ads:
After either the sale is made or it's been a very long time, some really good comments come out (maybe un-related) OR the thread drifts off into unknown territories and actually gets interesting. Usually way better than an ad with 342 photos in three axes, spaced at 15º apart when, really, 6 friggin photos of the car and a decent description would do. If you want more, PM the seller.
